WATER-DISTRIBUTING MEANS.

Specification of Letters Patent. Patented NGV. 2, 1920,

Application filed April 21, 1917. Serial No. 163,682.

To all 'whom it may concern Be it known .that I, 4JOHN A. BROOKS, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Water-Distributing Means; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of thisspecication.

This invention relates to water distributing means, and particularly to means for controlling the successive distribution of water to different discharge pipes in a multiple pipe sprinkling or water supply system.

In most public water supply systems residences are provided with water mains which are too small to supply more than three or in numerous forms, only a few of ysuch forms four sprinkler heads at one time without a material loss of pressure, and it has therefore been necessary in equipping lawns with sprinkling systems to either provide a plurality of supply mains, each having a lim-^ ited number of sprinkler heads, orto per@ mit one set -of sprinklers tooperate for a while, and then another, and so on until the area to be watered has been covered.

The primary object of my invention is the provision of simple and efficient means which is automatically operable to obtain a timed successive distribution of water. to different distributing lines from/a common source of supply, whereby to obviate the necessity of having different distributingl lmeans and also of manually attending to the turning on and shuttingof of water in dif-V ferent distributing lines in order to keep up the distributing pressure,

The invention is fully described in the following specilication, and while, in its broader aspect, it is' capable of embodiment arel illustrated inthe accompanying dra/win s, in which--` igure 1 is-acentrallongitudnal section of the preferred form'ofwater distributing means embodying theinvention, and. Fig. 2 is an enlarged fragmentary sectionofa por-4 tion thereof slightly mndiied.

casing of tubularl form in cross-section, in

the present instance, and forming the chamchamber 3 being the uppermost, in the pres- `ent instance, and the larger in diameter.

A water supply pipe 4 is tapped into the casing 1 in communication with the upper end portion of the chamber rality of water distributing 7 lead from said chamber in substantially equidistantly spaced relation longitudinally thereof and at one side of the supply pipe, as shown. The top of the chamber 3 is closed by a cap 8 having a fluid escape passage 9 therein which is normally closed to the chamber 3 by an outwardly seating valve 10, the stem 11 of which projects without the cap to permit the application of 'pressure to its outer end to unseat the valve when vdesired. The valve is normally held seated by a spring 12, which bears outward against the collar 13 carried by the valve stem.y

A plunger 14 is mounted for reciprocatory movements in the chamber 3 and has alholl low stem l5 projecting therefrom intothe chamber 2, said stem, in the present infy stance, being of suliicient length to extend to adjacent to the bottom of the chamber 2 when-the plunger 14 is at the bottom of its chamber. The stem l5 carries three cups or plunger members 16, 17 and 18 `which have a sliding fit in the chamber2 and are longitudinally spaced, as shown.

The stemV 15 is provided with enlarged openings or perforations 19 above the upper cup 16 and with outlet openings or perfora-l ktions 2O between the cups 17 and 18, all of said perforations opening communication the set of outlet pipes 5, 6 and 7 at `all times, andthe cups 17 and 18 are so positioned that theyvv are disposed below the set of outlet pipes o r'at the opposite side thereof to the j inlet pipe when the plunger is at the lower end of its str'oke, as showninF ig. 1. -The space between the cups 17fa`nd 18 is preferably less or not greater than the space be-Y 2 and a` plu. plpes 5, 6 and tween the outlet` passages of successive pipes 5, 6 and 7, .so that-the outletopenings 20 in the stem have communicationlwith only one outlet pipe at a time duringaraising or lowvering of the stem. 'i Referring to the draW1ngs1 deslgnates a` The plunger 14 has a` small` passage 21 sure through the tributing means it ment of the plunger. The chamber 2 provided in the bottom thereof with a drainage passage 24.

In ,the use of this form of my water disis set for operation by merely pressing on the valve stem 11 to unseat the valve 10 to release the compression in the chamber 3 above the plunger 14. The

water pressure which 1s constantly present in the chamber 2 between the plunger 14 and cup 16 due to the connecting of such space with a source of water supply under prespip'e 4, acts against the under side of the plunger 14 and forces such plunger and attached stem to the limit .of its inward movement, it being understood that the valve 10 is retained open until the plunger has reached the limit of its upward movement. The slow leakage of water through the passage 21 into the space above the plunger 14 causes the plunger and attached parts to slowly lower, the speed of such lowering being determined by an adjustment of the valve 22. It will be understood that the space between the cups 17 and 18 is in communication with the source of water supply through the inlet and outlet v perforations 19 and 20 and stem 15 so that during a descent ofthe plunger and stem the water under supply pressure is first distributed to the pipe 5 then to the pipe 6 and then to the pipe 7, and`so on for the number of distributing pipes provided during the period of communication of the space between the cups 17 and l18 with each'of said pipes, as said space is successively moved into register therewith.

In order to preventthe water under pressure within the chamber 2 from passing out into the respective distributing pipes as the outlet openings 20 are successively moved into register therewith during an upward movement of the plunger and stem, the cup 17 may be carried by a sleeve 25 for limited sliding movements `on the stem 15 between the lower cup 18- and aistop-collar 26 on thev stem, the sleeve 25 serving as avalve Jfor closing the perforations 20 when the cup 17 is in its lowered position on the stem, as shown in Fig. 2. It is apparent with this construction that upon an upward move-' ment of the stem 15, the rictional coaction of the cup 17 with the casing 1 will tend to hold itA stationary within said casing until the stemhas moved upward a suilicient dis-n tance to place the openings 20 therein into register with the valve sleeve 25 and to bring the lower cup 18 into contact with the lower end of saidsleev-v, or the cup ward movement of the stem coaction of the; cup causes such cup to remain stationary 1n its elevated position until the stem has lowered aV suiiicientl extent to move the collar 26 into contact with the upper end of the sleeve 25, thus,efecting an uncovering of the outlet openings-20. y a

It is evident that I have provided simple and efficient means for obtaining a successive through different *conduits from a common supply main, and that thev distribution of water from each discharge conduit may be quite accurately regulated as to 4both time and quantity. It is also evident that in the forms of the invention whereinthe lowering movement of the plunger carrying stem is 15 the frictional controlled by the same water pressure with movement of the plunger's is not constant but varies with the water pressure 4and also that the quantity of -water distributed is substantially constant and does not vary with the pressure.

I wish it understood that my invention is not limited to use in connection with the distribution of water as specifically described herein, and also that it is not limited to the speciic arrangement, form or construction of the parts, as it is capable of numerous modifications other than those illustrated without departing from the spirit of the claims.

Having thus described my invention,

what I claim as new, and desire to secure by LettersPatent, is-
